their mains are available for the Borough High Street and
Stamford Street only. Their charge would be about £32
per lamp per annum, the Board providing at its own cost
all lamps, pillars, switches, boxes and other things requisite
for the installation. If they lighted Southwark Street
and Southwark Bridge Road in addition, i.e., all the five
streets named, they calculate that the expense to the
Board for the necessary plant of the two last-named streets
would be about £5,000. Of course this would not include
the cost of current to the lamps, nor the lamps, &c., for
the three other streets.
“The City of London Company have furnished more
detailed and definite information, together with a plan
showing the proposed distribution of light in all the five
principal streets. This scheme provides for 86 arc lamps,
placed about 120 feet apart. The Company would lay the
necessary mains and connections, and supply and fix posts,
lanterns, lamps, &c., for running the lamps. Their charge
would Per lamp for 3,600 hours per annum. Extra
lighting in time of fog, &c., would be charged for additionally,
and they would require a contract for 21 years.
"The cost of these 86 lamps would be £2,408 per annum.
They would only displace 166 gas lamps, without taking
into consideration the meter lamps at the refuges, &c. The
annual cost of lighting the whole of the district with gas
is about £2,000. There are about 590 lamps ; therefore the
cost of lighting the five principal streets by means of
electricity would be considerably more than that of the
whole of the district by gas, e.g.:—
86 electric arc lamps at £28 £2,408
166 gas lamps at £3 3s. 9d. £529
"Assuming the same ratio or proportion of electric lamps
to be required for the whole district, there would be 306
electric lamps as against 590 gas lamps; but, having regard
to the fact that many of the back streets are of irregular
conformation, having corners and recesses which require
special illumination, it is obvious that a larger proportion
would be required for the efficient lighting of them.
"Taking into consideration all the facts as above set
forth, the Surveyor is of opinion, that for the complete
lighting of the district, including all the principal centres
now served by special lamps and not included in the above,
about 400 arc lamps would be necessary, at a cost of about
£11,000 per annum."
